Yes, too many broad absorption devices. They are not thick enough to absorb much below 400hz is my guess, but clearly too much in the mid/high range. Think LEDE without the LE. I mean NO insult to anyone at Klipsch, but some diffusion is a good thing for listening rooms, be it from QEDs or just a wall!
All right, I hear what you're saying about the tweeter, I don't know that much about the drivers of the 802D, but I'm wondering what you are basing the palladium being the "more resonant" speaker? Or is this a guess? Based on the lectures of the owner of one of our local hi-fi shops (not an overbearing elitist looser like so many) the lack of cabinet resonance in the 802x is due to the excellent cabinet design: the materials are stiff and the curvature means no standing waves inside the cabinet. The Palladium speakers' boat-tail and tapered top design provide the same benefits of no parallel surfaces, and the materials are something like 3 layers of MDF, with extra "ribs" like a boat skeleton reinforcing the cabinet. I doubt they are any more resonant than the 802x, and the P-38F come in at an extremely similar price point.
Interesting observations.
